What’s Happening to Jupiter’s Great Red Spot? The Solar System’s Largest Storm Could Finally Disappear

Jupiter’s Great Red Spot (GRS), an easily visible anticyclonic vortex and the largest such vortex in the Solar System, has intrigued scientists since it was first observed through telescopes centuries ago. Recent research, including simulations and space mission data, has investigated its formation, stability, and the possibility of it shrinking or disappearing in the future. Credit: NASA, ESA, A. Simon (Goddard Space Flight Center), and M.H. Wong (University of California, Berkeley)Jupiter’s Gr ...

Rethinking Dieting: Researchers Discover Why Fasting Doesn’t Always Equal Fat Loss

Scientists at Scripps Research have discovered that in Caenorhabditis elegans, a molecule produced in the gut during fasting travels to the brain and blocks fat-burning signals. This finding, which sheds light on the communication between the gut and brain, suggests that fasting may have benefits beyond simple calorie restriction. The study highlights the potential for new treatments targeting metabolic diseases by mimicking gut hormone actions.Scientists at Scripps Research have identified a mo ...

Notes on talk 1. anabelian geometry: introduction

1. What is contained in “Galois type” data?Gauss: The regular $n$-gon can be constructed by straightedge and compass if and only if $n = 2^{k}p_{1} . . . p_{r}$ where $p_{i} = 2^{2^{n_{i}}} + 1$ are Fermat primes. For example, $n = 17$. (Based on the study of the extension $\mathbb{Q}(\xi_{n})/\mathbb{Q}$ and cyclotomic polynomials). Here the key is that the hidden symmetries are in the Galois group action (not in the geometric symmetry). Later we will consider the “hidden” structures in the abs ...

A New Perspective on the Universe’s Expansion

The universe undergoes expansion, and the rate of this expansion is characterized by the Hubble-Lemaitre constant. However, controversy surrounds the actual magnitude of this constant, as different measurement techniques yield conflicting values. This discrepancy, known as the “Hubble tension,” presents a perplexing challenge for cosmologists.The image shows the distribution of matter in space - (blue; the yellow dots represent individual galaxies). The Milky Way (green) lies in an area with lit ...
